A perfect match: Dapr & Azure Container Apps
summary
Shows a runnable microservice sample that wires Azure Container Apps with Dapr sidecar injection to solve service discovery, state and pub/sub. Builds three services (traffic control, fine collection, vehicle registry), a browser simulator and a Mosquitto MQTT broker, using MQTT bindings, Cosmos DB state store, Service Bus pub/sub and KEDA for CPU autoscaling; the demo mostly works end‑to‑end and sends emails via an SMTP binding. Notes two real limits: only one TCP/HTTP Ingress port per app (broke the websocket MQTT UI) and lack of custom Dapr app config or pinned Dapr version in ACA.
